Opal-HN (Hyaline) on Smoky Quartz

One does not often come across well defined hyaline from the Erongo area, most often it is a thin dusting or light coating. This quartz crystal is covered with a thick layer of this highy fluorescent material (Very bright green under the SW UV lights). A great specimen, even better when one pops it under the UV lights..
